According to fossil record, the earth has experienced a number of mass extinction events. At least three of the events mark severe loss of calcifying organisms due to ocean acidification.

从化石记录知道地球曾发生数度的物种灭绝，其中至少有三次海洋钙化生物承受最大损失，原因是海水缺氧或海洋酸化。

The loading rates of NH〓-N removal for aerobic reactor and NO〓-N denitrified for the first anoxic reactor are 1. 01 and 0.94kg/m〓.

The results showed that C/N ratio had great effect on denitrifying dephosphatation.

在厌氧/缺氧(A2)SBR反应器中考察了C/N比对反硝化除磷效果的影响。

By controlling the nitrate concentration in the anoxic stage,the methods and effects of inducing Denitrifying Phosphate Accumulating Organisms were studied.

通过控制缺氧段硝酸盐浓度，研究了反硝化聚磷菌的诱导方法及效果。

The right atrium receives deoxygenated blood from vena cava.

右心房接受从大静脉来的缺氧血液。

Complete separation of oxygenated and deoxygenated blood permits more oxygen supply to tissue cells for respiration.

带氧血液和缺氧血液可完全，这样可容许更多氧气供应给组织呼吸，同时血压可，血流可，这可维持较的新陈代谢，哺乳类因而变得更。

Complete separation of oxygenated and deoxygenated blood permits more oxygen supply to tissue cells for respiration.

带氧血液和缺氧血液可完全分隔开，这样可容许更多氧气供应给组织呼吸，同时血压可高些，血流可快些，这可维持较高的新陈代谢，哺乳类因而变得更活跃。

MethodsFocal cerebral ischemia was produced by permanent occlusion of the proximal of the right middle cerebral artery. The neurologic status of each rat was carefully evaluated at 24 h after surgery. The cerebral infarction numbers of neurons and nissls stains ,the water content were measured. Acute incomplete cerebral ischema was induced by ligaturing bilateral carotid arteries. Anoxia was produced by close normobaric hypoxia.

方法电凝大鼠一侧大脑中动脉造成局灶性脑缺血，观察脑血舒通对大鼠行为、大脑皮质内脑梗塞区神经细胞数量、尼氏小体含量、脑组织含水量的影响；采用结扎小鼠双侧颈总动脉形成急性脑缺血模型，并进行了小鼠常压耐缺氧实验，观察小鼠存活时间。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
